TOP245GN General Description

TOP245GN is a highly integrated offline switcher made by Power Integrations. It is designed for low power offline power supplies that require high efficiency and low standby power consumption. The TOP245GN incorporates a 700V power MOSFET, a multi-mode controller, and various protection features into a single IC package. This allows for a compact and cost-effective solution for AC-DC power conversion in applications such as power adapters, chargers, and standby power supplies.Key features of the TOP245GN include a built-in 700V MOSFET with low on-resistance, which helps to minimize losses and improve efficiency. The multi-mode controller allows for the device to operate in different modes depending on the load conditions, optimizing efficiency over a wide load range.Additionally, the TOP245GN includes a suite of protection features such as overvoltage protection, overcurrent protection, and thermal shutdown to ensure safe and reliable operation. The device also offers a frequency jittering function to reduce EMI emissions, making it compliant with various EMC requirements.
